Description

Technical Field

[0001] This application relates primarily to the field of printing equipment, and more particularly to a printer. Background Technology

[0002] With the rapid development of smart payment technology, handheld POS devices are increasingly widely used in the retail industry, bringing great convenience to retailers and consumers. In payment scenarios requiring receipt printing, thermal printer functionality has become an essential feature of handheld POS devices. Considering the stringent portability requirements of handheld devices, most are equipped with small printer components. However, due to the high frequency of use of these printer components, they are prone to malfunctions or breakdowns.

[0003] Generally, when a small printer component malfunctions, whether it's for inspection, repair, or replacement, the entire machine usually needs to be completely disassembled. Currently, the assembly and disassembly of printer components are quite cumbersome for printers on the market.

[0004] As attached Figure 1 As shown, when assembling the printer 30, the printer assembly 108 needs to be fixed first using the paper tray bracket 104. After assembling the printer assembly 108, the paper tray bracket 104 also needs to be fixedly connected to other components. Therefore, if the printer assembly 108 needs to be removed during functional testing, troubleshooting, or replacement, the entire printer needs to be disassembled. This means removing all the housing fasteners 101, and completely removing the rear cover 102, motherboard assembly 103, paper tray bracket 104, battery cover 107, front cover 105, and side cover 106 before the printer assembly 108 can be removed.

[0005] The above-mentioned assembly and disassembly methods are not only inefficient, but also have obvious defects. They not only reduce the efficiency of assembly, manufacturing and maintenance, but also pose a high risk. During the disassembly process, other key components are easily damaged, which increases the manufacturing and maintenance costs of the product and the downtime of the equipment, thus adversely affecting the normal operation of the retail business.

[0030] This application refers to Figures 2-4 A printer 10 is shown, wherein, Figure 2 A schematic diagram of the printer component 11 in printer 10 is shown. Figure 3 and Figure 4 A schematic diagram of the overall structure of printer 10 is shown. Now, in conjunction with... Figures 2-4 The specific structure of printer 10 is described in detail. For example, printer 10 is a handheld mini printer.

[0031] In this embodiment, the printer 10 includes a printer assembly 11, a base 12, and two printer fasteners 13. Specifically, the printer assembly 11 includes a male connector 111 and two first fastening holes 112. The base 12 includes a female connector 121 and two second fastening holes 122. The female connector 121 is configured to be electrically connected to the male connector 111. The first fastening holes 112 and the second fastening holes 122 correspond one-to-one in space and number. The printer fasteners 13 pass through the first fastening holes 112 and the second fastening holes 122 to fix the printer assembly 11 and the base 12.

[0032] In other embodiments of this application, the number of the first fastening hole 112 and the second fastening hole 122 can be adjusted according to the number of printer fasteners 13.
